1. Technical Field
This disclosure relates to devices for holding tools and buckets and more specifically devices designed to be supported by a ladder.
2. Background
Workers who use extension ladders or step ladders (such as A-frame ladders) often have multiple pieces of equipment or tools that they need to use when they are on a ladder. For example, a painter may use a paint sprayer with a hose line, and have a paint roller that is used in conjunction. Other workers use equipment with electrical cords such as a drill, and have other tools that are needed at the same time. Painters or workers also use buckets, such as paint buckets with paint, to paint edges and corners where sprayers or rollers cannot properly reach.
Workers will often bring multiple tools and a bucket of paint up on a ladder, and store some of the tools on the rungs or steps of the ladder until needed, and rest the can or bucket of paint on a rung or a step. For example, a painter will bring a paint sprayer and a roller up on a ladder, and place the roller resting against a ladder rung or step while spraying, and then will place the paint sprayer resting on a ladder rung or step while using the roller to further spread the paint. The painter may then need to climb down the ladder with the paint sprayer and climb back up the ladder with a bucket of paint for the areas where the sprayer and roller did not reach. Further, while painting with the paint in the bucket, the painter may need to balance the paint can on the ladder to maintain three-point contact with the ladder while holding the paint brush and painting.
The past methods present a hazard as a cord or hose can trip the worker when it hangs onto the ladder rungs or steps, and the paint can or bucket can fall or distract the worker on the ladder while trying to balance the paint can and paint. When a tool with a cord or hose is stored on one of the ladder rungs or steps, the cord or hose will hang down along the rungs or steps of the ladder where the worker is standing. The hose or cord can interfere with the feet of the worker and cause a hazardous situation. The tool can also be damaged if the worker steps on the hose or cord, or accidently causes the equipment to fall.
Tools and buckets that do not have a cord or hose can also be hazardous when used on an extension ladder or step ladder, because the worker needs to hold the tool or bucket, or balance the tool on the ladder so that it will not fall when it is being used. If the tool is dropped the tool can break, or someone working near the ladder can become injured.
An example embodiment of a device 100 is shown in
The first inside surface 118 along the first side extension 124 may be facing the second end 114 of the longitudinal support portion 110.

In some embodiments the tool holder base 166 may include a second threaded opening 169 (shown in
A ladder support 176 is shown in
A first clamping structure may include the first brace 116 with the longitudinal support portion 110 and the first threaded rod 152. The first clamping structure may clamp onto the first edge 184 of the ladder support 176. A second clamping structure may include the second brace 130 with the longitudinal support portion 110 and the second threaded rod 160. The second clamping structure may clamp onto the second edge 186 of the ladder support 176. In some embodiments the device 100 may have only one threaded rod positioned between the first brace 116 and the second brace 130. The second brace 130 may be able to slide along the longitudinal support portion. In some embodiments the second brace 130 includes a second brace opening 148 that allows the second brace 130 to slide along the longitudinal support portion 110. The longitudinal support portion 110 is shown in the example embodiments as a round rod, but may be other shapes in other embodiments, and the second brace opening 148 may have a shape that corresponds to the shape of the longitudinal support portion 110. Other methods may be used to allow the second brace 130 to slide along the longitudinal support portion 110.
In some embodiments the first brace 116 may be attached to the first end 112 of the longitudinal support portion 110 in a fixed manner. For example, the first brace 116 may be attached with a bolt secured in a threaded portion of the longitudinal support portion 110. In another example the first brace 116 is welded to the longitudinal support portion 110, and in other embodiments the first brace 116 may be connected with adhesives, or formed as one piece with the longitudinal support portion 110. The first brace 116 may be fixed in relation to the longitudinal support portion 110 so that the first brace 116 does not rotate about the longitudinal support portion 110. In some embodiments with the first brace 116 fixed in relation to the longitudinal support portion 110, a stable clamp structure may be formed including the first threaded rod 152.
In some embodiments the second brace 130 may be separated from the device 100. The second brace 130 may be formed with a second brace opening 148 that may allow the longitudinal support portion 110 to fit through the second brace opening 148. In some embodiments the second brace opening 148 also fits over the tool holder base 166, so that the device 100 may be assembled by sliding the second brace opening 148 over the tool holder base 166 and past the second end 114 of the longitudinal support portion 110. In some embodiments the second brace 130 may be slidably connected to the longitudinal support portion 110 to allow for the device 100 to be attached to different ladders having variation in the width 178 of the ladder support 176. The second brace 130 may slide to allow the device to clamp around the second edge 186 of the ladder support 176.
A user may place the first brace 116 against the first edge 184 of the ladder support 176, and slide the second brace 130 away from the second threaded rod 160 to allow the second brace 130 with the second clamp extension 138 to go around the second edge 186 of the ladder support 176. The user may then slide the second brace 130 towards the second threaded rod 160 and against the second edge 186 of the ladder support 176. The user may then use the first hand-adjuster 156 and the second hand-adjuster 164 to move the first threaded rod 152 and the second threaded rod 160 against the ladder support 176, clamping the device 100 to the ladder support 176. The user may insert a tool holder 182 into the longitudinal channel 172 and align a notch 244 on the tool holder 182 with the threaded tightening rod 174. The user may turn the threaded tightening rod 174 to fix the rotational position of the tool holder 182 relative to the tool holder base 166. The user may then attach a tool to the tool holder 182 and have a safe place to store a tool while on a ladder.
In some embodiments the device 100 may have only one threaded rod such as the first threaded rod 152. The first clamp surface 154 may be any size that would fit between the first inside surface 118 and second inside surface 132. In some embodiments the first clamp surface 154 may have a portion that is directly opposite the first brace clamp surface 128, which may provide a better clamping function on one edge of a ladder support than if at least a portion of the first clamp surface was not directly opposite a portion of the first brace clamp surface 128.
The device 100 may be attached to a ladder support 176 as shown in
The first clamp extension 126 and the second clamp extension 138 may extend towards each other to securely hold the device 100 to the ladder support 176 when at least the first threaded rod 152 is tightened. The second threaded rod 160 may also be tightened against the ladder support 176. A tool holder 182, such as the bucket holder shown in the example drawings, may be supported by the device 100 by inserting a portion of the tool holder 182 into the tool holder opening 170 and into the longitudinal channel 172. The threaded tightening rod 174 may be tightened against the portion of the tool holder 182 in the longitudinal channel 172 thereby securing the tool holder 182 in place.
In some embodiments the tool holder 182 may have a notch 244 in the portion to be inserted into the longitudinal channel 172, and the threaded tightening rod 174 may be inserted into the notch portion of the tool holder 182, thereby limiting the ability of the tool holder 182 to rotate relative to the tool holder base 166.
An example embodiment of a tool holder may be a bucket holder 200 as is shown in
In some embodiments the handle retainer 222 may extend substantially perpendicular to the first portion 220. The handle retainer 222, may have a bend 233 and may have a first end 232 and a second end 234. The first end 232 may extend from the first portion 220. The second end 234 may be parallel with the first portion 220 and may extend towards the near end 227 of the first portion 220. In some embodiments the handle retainer 222 may not have a bend, and may extend perpendicular to the first portion 220, or may extend at an angle so that the second end 234 is closer to the near end 227 of the first portion 220 than the first end 232 of the handle retainer 222. The bend 233 in the handle retainer 222 may be an angle between two perpendicular parts, and it may also be a curve that is continuous over a portion or all of the handle retainer 222.
The bucket stabilizer 224 may include a support arm 238 and a stabilizer arm 236. In some embodiments the concave portion 226 may be the stabilizer arm 236. The concave portion 226 may extend in a direction substantially perpendicular to the support arm 238. The concave portion 226 may be attached to the support arm 238. The concave portion 226 may have at least one end that is further from the support arm 238 than the place where the concave portion 226 is connected to the support arm 238. The support arm 238 may extend from the far end 228 of the first portion 220.
The stabilizer arm 236 may have a grip layer 240 on at least a portion of the stabilizer arm 236.
The near end 227 of the first portion 220 may have an attachment structure configured for attaching the first portion 220 to a base 350 (shown in an example embodiment in
In some embodiments the first portion 220 and the support arm 238 may be formed by bending a metal rod at an angle. The handle retainer 222 may be welded to the first portion 220 at a position set back from the far end 228 of the first portion 220.
In some embodiments the base may be attached to a ladder and may be supported by a ladder. The ladder may be an A-frame ladder, or it may be an extension ladder. The base may be supported by the ladder or other device in various ways.
An example embodiment of a ladder assist tool 300 is shown in
In the illustrated example the ladder assist tool 300 may be placed into the rung of a ladder such as an extension ladder or an a-frame ladder with open rungs. The base 350 may fit tightly into the hollow rung, and the base extension 323 may extend into the hollow ladder rung and out the other side of the ladder. The second end 327 of the base extension 323 may come out the other side of the ladder. The holes 329 may be exposed after the ladder assist tool 300 is fully inserted into the rung of the ladder, and a pin such as a cotter pin, may then be inserted into one of the holes 329 to retain the ladder assist tool 300 in place.
In some embodiments the base extension 323 may be a round metal rod or steel pipe. In other embodiments the base extension 323 may be made from other metal material, or from non-metallic materials. The base extension 323 is shown in the illustrated embodiment as round. In other embodiments the base extension 323 may be other shapes including square, triangular, hexagonal, or other shapes.
The bucket holder 200 may support a bucket or pail or tray with a handle or can of paint and allow a worker to safely navigate a ladder or use other tools without holding or balancing a paint can or other device.
The bucket holder 200 may be attached to the base 350 in many different ways. In some embodiments the bucket holder 200 may be attached to the base 350 with a threaded end 246 that may be used to secure the bucket holder to a threaded piece in the base 350 or a threaded piece in the base extension 323. A locking nut may be used to secure the threaded end 246 and the bucket holder 200 in a preferred rotational position. In some embodiments a notch 244 may be positioned and configured to allow a threaded rod with a flat end that may be passed through a threaded portion in the base 350 to contact a flat portion in the notch 244 and thereby prevent rotation of the bucket holder 200 relative to the base 350. In other embodiments the base 350 may be secured to the base extension 323 by welding, and the base 350 may be formed or assembled around the base extension 323. Other embodiments may use adhesives, or structures to secure the bucket holder 200. The base 350 may be configured to allow multiple attachments so that one type of support structure or tool holder may be replaced by a different type of tool holder based on the needs of the user.
In some embodiments the bucket holder 200 tool may be inserted into a ladder where the top of the ladder rungs are generally horizontal. The preferred position of the bucket holder 200 may also be generally horizontal. The base 350 in this embodiment may have one or more generally flat top portions that aligns the ladder assist tool 300 to the top of a ladder rung and may prevent the ladder assist tool 300 from rotating. In some embodiments the ladder assist tool 300 may be generally flat and within a horizontal plane, which may be aligned to be substantially parallel to the top of the ladder rung.
The above embodiments are illustrated and discussed as examples. Variations may be made in the shape, materials, function and operation of the above embodiments and remain within the invention as claimed. The terms “right” and “left” are used for the purpose of illustration and not in a restrictive manner. The first brace 116, for example, may be on a user's left or right, and does not indicate any orientation to a person or thing. For example, the base 350 is shown with a flat side on top. In other embodiments the base structure may be round without a flat side and may fit into the hollow rung of a ladder.
While the principles of the invention have been made clear in illustrative embodiments, there will be immediately obvious to those skilled in the art many modifications of structure, arrangement, proportions, and methods, the elements, materials, and components used in the practice of the invention, and otherwise, which are particularly adapted to specific environments and operative requirements without departing from those principles. The appended claims are intended to cover and embrace any and all such modifications, within the limits only of the true spirit and scope of the invention.
